Few extinct species have been as genetically well studied as the woolly mammoth (Mammuthus primigenius). Several studies have revealed that the species' Late Pleistocene history was characterized by a complex series of demographic changes and genetic turnovers. Changes in climate appear to have been a major driver for range dynamics in the woolly mammoth, and likely contributed to the end-Pleistocene extinction of the species across most of its range. However, the extinction of the last remaining population of woolly mammoth, on Wrangel Island, still remains a mystery. Analyses of both mitochondrial and autosomal variation suggest a stable and genetically variable population for thousands of years, until the species finally disappeared.
